Have you verified if the problem lays into UML or into the guest distribution? I.e. if the "dd" version you're using is not up-to-date, the program itself won't allow that (and until very recently, i.e. 2 months ago, wget has this problem - don't know if that has yet been fixed). And since you're talking about Debian, that seems likely. Strace the offending program, grep for "open" and verify that O_LARGEFILE is passed between the params. Or try doing that command on the root_fs directly, here's the road to do the test, which is done via creation of a sparse file: dd if=/dev/zero of=test.img bs=$((1024*1024)) seek=$((3*1024) count=1 If this doesn't work, then your guest fs has a broken dd (and probably glibc too) and you should upgrade. It's even possible that the host system itself is too outdated and hasn't support for this stuff - give all version information, please.
